[Estimation of body composition based on total body water determination using phenazone for assessment of body fat gain in cattle. 1. Relationship between body fat content and live weight].
Body composition based on total body water analysis using phenazone were estimated in 251 beef heifers, aged 3 to 17 months, 27 beef bulls aged 15 months and 200 Holstein dairy cows of different age and stage of lactation. Correlation coefficients between body fat content and live weight were estimated to be between 0.59 and 0.97 for groups of animals. In beef heifers there was a fat gain of 294 g per live weight gain of 1 kg, in beef bulls 247g, in cows until third lactation 418 g and 731 g respectively 791 g in entirely full-grown cows. Cows of first lactation showed loss in body fat content with simultaneous gain in live weight. Hence, using body weight for assessment of change in body fat content is dependent on special prerequisites, which will be discussed.
